L'Equipe report that all three players have signed on with the Parisian outfit until 2019, with their contracts previously set to expire at the end of the new season.

Szarzewski missed the tour of Australia in June through injury, but is the most experienced of the three having won 79 caps. By the time his contract expires he will be 36.

Le Roux, 25, has eight caps for France while prop Ducalcon, 30, has won 19 so far.

Racing's turnover has been significant ahead of the 2014/2015 season, with eight players departing and nine arriving including France stars Brice Dulin and Antoine Claassen along with young South African fly-half Johan Goosen.
